The term data compression identifies reducing the number of bits of data that should be saved or transmitted. This can be achieved with or without losing data, which means that what will be erased during the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the information and the quality will be identical, whereas in the second case the quality will be worse. There're different compression algorithms that are better for various sort of data. Compressing and uncompressing data normally takes lots of processing time, which means that the server executing the action should have ample resources in order to be able to process the data quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 in the binary code rather than storing the particular 1s and 0s.
Data Compression in Cloud Website Hosting
The ZFS file system that operates on our cloud web hosting platform uses a compression algorithm called LZ4. The latter is considerably faster and better than every other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that very quickly, we are able to generate several backup copies of all the content kept in the cloud website hosting
accounts on our servers daily. Both your content and its backups will need less space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the hosting servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting
account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and definitely the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data quicker than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will speed up every site that runs on a platform where this algorithm is enabled. The high performance requires a lot of CPU processing time, that is provided by the multitude of clusters working together as a part of our platform. In addition, LZ4 allows us to generate several backup copies of your content every day and keep them for one month as they will take a smaller amount of space than typical backups and will be created much faster without loading the servers.
